ADF134B-B05TA0-BS06-A2N3
ADF Main Spindle Motors
Bosch Rexroth Indramat manufactures the ADF134B-B05TA0-BS06-A2N3 within the ADF Main Spindle Motors series. This unit is a liquid-cooled asynchronous motor designed to drive machine-tool spindles in continuous-duty industrial automation. By circulating coolant internally, it maintains constant thermal conditions at high speed, while the asynchronous rotor provides stable torque. The ADF134B-B05TA0-BS06-A2N3 therefore serves as the central rotating element that couples to the machining spindle and accepts commands from a dedicated drive controller.
Mechanical dimensions follow the series coding. The motor employs a 134 frame size and a B length, giving a compact envelope suitable for direct flange mounting. Power conductors exit to Side A through a connector/plug enclosure, and electrical behavior matches the BS winding code supplied by the manufacturer. A plain shaft transfers torque to the tool holder, and the side B face is delivered without a second shaft end. Standard rolling bearings carry radial and axial loads in typical machining duty.
Thermal stability comes from closed-loop liquid cooling that enters through an axial line with connection thread 1/4", keeping stator temperature uniform during long cycles. The power connector is positioned at the top of the housing so cable bends stay clear of the coolant manifold. Rotor balance quality conforms to S1 DIN ISO 2373, supporting high rotational speeds without excessive vibration, and position data are returned via digital servo feedback for tight velocity control. The motor is supplied without a holding brake, without a shaft seal ring, and with standard bearings, so any static holding force or fluid isolation must be implemented externally. As a liquid-cooled asynchronous motor, the design relies on external coolant, flange alignment, and the plain single shaft to streamline spindle integration.
